SELF-HEATING CURLINGr-IRON.

Specification 0f Letters Patent.

Patented Aug. 5,1913.

Application led November 29, 1912. Serial No. 734,099.

To all 10710170525 may concern.'

Be it known that I, HAROLD G. NiLsoN, a citizen of the United States7 residing at 608 Arcadial Court. Kalamazoo, Michigan, have invented certain new and useful Improvements in Self-'Heating Curling-Irons, of which the following is a specification.

This invention relates to improvements in self-heating curling irons.

The main objects of this invention are,- FirstT to provide an improved self-heating curling iron having an igniting means which is very simple and convenient in its operation.

Second, to provide an improved self-heating curling iron adapted for the use of liquid fuel such as alcohol or gasolene or other hydrocarbons, which may be placed in any position while charged with fuel without danger of the fuels spilling or leaking. Third,

to provide an improved self-heating curlingA iron which has the above advantages, which is very quickly heated.

Further objects, and objects relating to structural details, will definitely appear from the detailed description to follow,

I accomplish the objects of my invention by the devices and means described in the following specification.

The invention is clearly defined and pointed out in the claims.

A structure which is a preferred embodiment of my invention is clearly illustrated in the accompanying' drawing forming a part of this specificationj in which:

Figure I is a side view of my improved self-curling heating iron mounted upon its support. Fig. II is a. detail view mainly in vertical central section. Fig. III is an enlarged detail view in vertical centralrsection showing details of the fuel feed chamber, the feed valve7 the wick holder and ig- In the drawing similar reference characters refer to similar parts throughout the several views. and the Sectional views are taken looking in the direction of the litt-le arrows at the ends of the section lines.

My improved self-heatingcurling iron as embodied in the structure illustrated, comprises a hand piece 1 having a fuel reservoir 2 therein.

The tubular curling rod member 3 is tapered toward its outer end and is provided with a fuel feed or wick chamber fic at its inner end or base. The chamber it is open at th-e bottom7 its outer end being closed by the wall 5 having a wick holder 6 thereon.

The curling rod member 3 is removably mounted on the hand piece, being preferably shouldered at 7 and threaded into the hand piece at 8.

The wick 9 is arranged in the wick holder 6, its lower end being surrounded by the absorbent material 10 within the feed chamber.

The end wall 11 of the reservoir 2 is provided with a valve seat 12 for the conical valve 13. The valve stem 11 of the valve 18 is arranged longitudinally through the fuel chamber and provided with a finger piece 15 threaded into the lower end of the hand piece.

By adjusting the finger piece, the valve is opened or closed. The valve is provided with a shank 16 having a tongue 17 arranged in a slot 18 in the end of the stem, the shank being secured by t-he pin 19 engaging a slot 2O in the stem. This permits a limited longitudinal movement of the shank in the stem.

A sleeve 21 is carried by the stem and embraces the joint between the shank and the stem. On this sleeve is a coiled spring 22 acting against the valve to hold it yielclingly in its seat. The object of this isto permit contraction and expansion of thev metal as it is'heated and cooled without straining the parts and without opening the valve.

The linger piece 15 is provided with passages 23 normally closed by the `plug 24. rIhis plug is provided with a socket 25 for the nipple 26 on the cup-like support 27. This support 27 is adapted as a funnel for filling the reservoir, and also as a support.

The clamping member 28 is pivoted at 29 on the arm 30 carried by the curling rod. memberr 3. The spring 31 holds the clamping member normally closed.

A lighting device comprising the abrad ing wheel 32 mounted' on the support 38 the block 0f 'pyrOPhrOiaateral 34, is

provided. The supportI 35 is mounted on the curling rod member 3 opposite the clamp member 28. rihe pyrophoric block 34 is yieldingly supported by the coiled spring 35, the adjustment of the tension of the spring being effected by the screw 36.

The member 3 is provided with air inlet openings 37 about the Wick holder, and with an opening 38 opposite the sparking device, so that vvhen the abradent 32 is rotated, the sparks are thrown through the opening across the Wick.

The member 8S is provided with an opening 39 opposite the opening 38, the opening 39 being considerably larger than the opening 3S and extending some distance toward the end of the member 3.

In use, the valve 13 is opened to admit a quantity of the fuel into the fuel feed chamber and is then closed. The fuel is taken up by the absorbent material and by capillarity passes out through the wick. Gasolene or like fuel is preferably used as it readily volatilizes soV that it may be quickly ignited by means of the sparking device.

In igniting, the clamp member is preferably held open until a brisk blaze is secured. The ar 1angement of the openings 38 and 39 described, tends to carry the heat away from the igniting device and up the clamp member and the curling rod.

The device may be used a number of times Without relling the reservoir and can be packed or transported Without danger of spilling the fuel.

I have illustrated and described my improved self-heating curling iron in detail in the form in which I have embodied the same. I have not attempted to illustrate or describe the various modifications Wnich I contemplate as such modifications Will no doubt be readily understood by those skilled in the art to which this invention relates. I desire, however, to be understood as claiming my improvements specifically in the form illustrated, as Well as broadly Within the scope of the appended claims.

Having thus described my invention, What I claim is nen7 and desire to secure by Letters Patent is:
